JET on BBC Horizon | 11/01/2011

When looking at the extremely hot end of the scale, JET – which has observed temperatures of up to 300 million degrees Celsius (20 times hotter than the Sun) – was an obvious place to come. CCFE diagnostic scientist Dr Joanne Flanagan explained why such high temperatures are needed in fusion research and how they are measured.
